Chemist knows that polyester resin does't like styrene , carbon black does't like magnetite ; Question mark is what if they get along each other , is it possible to merge together ?

Carbon Black embedded on Magnetite ?

Yes, it is possible with new technology and we made it and called IPM®-HYBRID UNIVERSAL

You could not believe that it works very same toner in such a different printers and MFP's which have different technologies.

Please try most painful machines like Samsung SLM 2020 printers , like Hp m102 printers, on %100 new Hp or Samsung cartridges recycling. Lexmark Optra series even Canon copiers as above mentioned; YOU WILL NOT BELIEVE TILL YOU TRY.
